Adaptive Decision Feedback Equalizer using the Delta Operator

The problem of the delta operator formulated adaptive equalization is considered by the application of the delta operator least mean squares algorithm into the design of adaptive equalizer. The algorithm of adaptive decision feedback equalizer based on the delta operator (Delta-ADFE) is presented, and the updating-parameter expressions of decision feedback equalizer are also given. Simulation results show that the proposed Delta-ADFE algorithm has the better filtering performance and the equalizing effect than that of the traditional ADFE algorithm using the shift operator
